Remove empty folders

B

brhessel

Looking for some help. I am scripting the move of files with a last
access time older than 30 days and I would like to remove the folder
that contains these files if that folder is empty after the files are
moved. Here is what I have so far to move the files and maintain the
folder structure. (Thanks to other posts on here)

$now = get-Date
get-ChildItem -recurse *|Where-Object{$_.LastAccessTime -le
$now.AddDays(-30)}|move-item -Destination {join-path 'Z:'
$_.FullName.SubString($pwd.Path.length)} -PassThru -Whatif

any help is appreciated.

{del $_.fullname -whatif}}

Something like this should remove the empty folders. Modify the "c:\" in the
getfolder to point to the root of the folders you want to test

$fso = New-Object -com "Scripting.FileSystemObject"
$folder = $fso.GetFolder("C:\")

foreach ($subfolder in $folder.SubFolders)
{
If ($subfolder.Size -eq 0)
{

remove-item $subfolder.Path -Verbose

}


}

If you want to include hidden and read-only empty folders include the -force
parameter:

To see if a folder is empty:

# True if empty
!(gci <path> -fo)

To remove all empty folders under <path>:

ri (gci <path> -r -fo | ? {$_.PSIsContainer -and !(gci
$_.fullName -fo)}).fullName -fo

Scratch my previous answer, I tested it and only worked on the first empty
folder. This one does the job:

To see if a folder is empty:

# True if empty
!(gci <path> -fo)

To remove "all" empty folders under <path>:

foreach($dir in @(gci <path> -r -fo | ? {$_.PSIsContainer -and !(gci
$_.fullName -fo)})) {ri $dir.fullName -fo}

I'm not sure this quite works.

The problem is that you may have a tree like this

|
|\DIR1
| |\DIR1.1 (empty)
| \DIR1.2 (empty)
\DIR2 (empty)

The above script will remove DIR1.1, DIR1.2, and DIR2, but it will leave DIR1 because when it was checked it wasn't empty, it contained Items DIR1.1 and DIR1.2. With a massively deep tree, this leaves many branches untrimed.

This is what I came up with:

foreach ($dir in @(gci . -r | where {$_.PSIsContainer} | sort -descending fullName)) {ri $dir.fullName | where {!(gci $dir.fullName)}}

First I build a list of all possible directories and I sort it decending so that the parent directory is always after the children in the list. Then I iterate over that list and only remove the directory if it has no children. Since I am working from a list of directories created before I start deleting, this lets me check each directory along the way and should prune everything.

To use, CD to the directory you want to prune, and run the above statement.

RE: Remove empty folders - Kiro

Slight change... the old way kept prompting me... I relized that I should
have been using an if statement instead of where... try this instead.

foreach ($dir in @(gci . -r | where {$_.PSIsContainer} | sort -descending
fullName)) {if (!(gci $dir.fullName)) {ri $dir.fullName}}

Thanks for catching that and fixing the script. I'm guilty of not testing
_thoroughly_ :)

Re: how about characters [ and ] in directory names?

Since you did not supply a parameter name when using Remove-Item,
$dir.fullName is used as value of the -Path parameter which supports
wildcards. So, if the directory name was c:\what[ever], the CmdLet would
try to find an item whose name starts with c:\what and then ends with
one of the letters e, v or r. Try the -LiteralPath parameter instead:
Remove-Item -LiteralPath $dir.fullName -WhatIf
